A method for setting an orthodontic archwire involves creating a model of a patient's dental anatomy and manipulating the virtual teeth to a desired finished condition. Virtual orthodontic brackets are installed on the virtual teeth. The virtual teeth with their virtual orthodontic brackets are returned to their original positions. A CAD model of a fixture can then be designed for setting a wire in a desired shape based on the arch slots in the virtual brackets, with activations so that the resulting archwire will store and transfer corrective energy to the patient's teeth. A CNC milling machine is employed to produce a fixture based on the CAD model of the fixture. The fixture is then assembled to hold a wire. The fixture and wire are heated to a predetermined temperature for a period of time to set the wire.
